Turtlebot not moving

When I implement the turtlebot progress by the recording part in the site http://wiki.ros.org/rosbag/Tutorials/Recording%20and%20playing%20back%20data everything runs smoothly. But while the turtle show up, I cannot make it move by the arrow on keyboard. It just freeze in the window. Is running the turtlebot the most fundamental testing in the ros system? Can someone give me some advices? Thanks a lot.

From your tutorial :

Pressing the arrow keys on the keyboard should cause the turtle to move around the screen. Note that to move the turtle you must have the terminal from which you launched turtlesim selected and not the turtlesim window.

So if you clicked somewhere else after rosrun turtlesim turtle_teleop_key it's normal. Just click on this terminal to be able to use the keyboard.
